Detailed Description

template<class OBJECT>
class bslma::ExceptionGuard< OBJECT >

This class provide a mechanism to verify the strong exception guarantee in exception-throwing code. On construction, this class stores the a copy of an object of the parameterized type OBJECT and the address of that object. On destruction, if release was not invoked, it will verify the value of the object is the same as the value of the copy create on construction. This class requires the copy constructor and operator == to be tested before use.

Constructor & Destructor Documentation

template<class OBJECT >

bslma::ExceptionGuard< OBJECT >::ExceptionGuard	(	const OBJECT *	object,
		int	line,
		Allocator *	basicAllocator = 0
	)

Create the exception guard for the specified object at the specified line number. Optionally, specify basicAllocator used to supply memory.

template<class OBJECT >

template<class ALLOCATOR >

bslma::ExceptionGuard< OBJECT >::ExceptionGuard	(	const OBJECT *	object,
		int	line,
		const ALLOCATOR &	basicAllocator
	)

Create the exception guard for the specified object at the specified line number. Optionally, specify basicAllocator used to supply memory.

template<class OBJECT >

bslma::ExceptionGuard< OBJECT >::~ExceptionGuard

(

)

Destroy the exception guard. If the guard was not released, verify that the state of the object supplied at construction has not change.

Member Function Documentation

template<class OBJECT >

void bslma::ExceptionGuard< OBJECT >::release

(

)

Release the guard from verifying the state of the object.

template<class OBJECT >

void bslma::ExceptionGuard< OBJECT >::resetValue	(	const OBJECT &	value,
		int	line
	)

Reset the expected state of the guarded object, if an exception should propagate past this guard, to the specified value, which is set from the specified line.
